The velocity at which new functionality can be created is reduced when you have technical debt. Also, it causes a greater percentage of the product's budget to be spent on maintenance of the product.

There is no activity gap between Sprints. A new Sprint starts immediately after the conclusion of the previous Sprint.
Q: Who is responsible for estimating a Product Backlog item's size ?
The Developers who will be doing the work are responsible for the sizing. The process of estimation should involve collaboration and communication between the Product Owner and the Developers to ensure a shared understanding of what is required to complete the item.
The Product Owner may influence the Developers by helping them understand and select trade-offs.
Q: When should a Developer on a Scrum Team be replaced?
Replacing a Developer on a Scrum Team should be as needed, while taking into account a short-term reduction in productivity, team cohesion and performance.

The duration a Product Owner should engage with the Developers depends on several factors such as Complexity and uncertainty of work, Scrum Team maturity and experience, Urgency of customer feedback , market conditions or shift in Stakeholder priorities, participation in key Scrum Events. However, the Product Owner should spend time with Developers as much as needed to ensure clarity, remove blockers and maximize the value of the product resulting from the work of the Scrum Team.

The Product Owner is responsible for maximizing the product's value and managing the Product Backlog, while the Scrum Master is responsible for promoting and supporting Scrum by helping everyone understand Scrum theory, practices, rules, and values. Both accountabilities are essential for the success of the Scrum Team, and their participation and availability can significantly impact the team's outcomes.
